Available in Windows, Mac and Linux

RealNetworks has issued an update that patches four security holes in its RealPlayer jukebox program, including a critical flaw that vulnerability tracker Secunia published today.

The company says versions for Windows, Mac, Linux operating systems are all vulnerable to at least one of the flaws and that users should update as soon as possible.

Among the bugs that are fixed is a flaw within the handling of frames in Shockwave Flash (SWF) files that can be triggered by a heap-based buffer overflow. Secunia published this advisory warning of the vulnerability, which carries the common vulnerability and exposure designation CVE-2007-5400.

A second bug, CVE-2007-1309, affects the RealAudioObjects.RealAudio ActiveX control, which doesn't properly manage memory for the Console property, allowing the remote execution of code. Details weren't yet available about the remaining two vulnerabilities, CVE-2008-3064 and CVE-2008-3066.
